Hi I was wondering if anyone knows how to make a shield for the Arduino that could monitor bacteria. So heat, growth, health maybe or what mutations/if it has mutated.

Can you tell more about the bacteria experiment?

some quick ideas - thinking oud loud:

- An Arduino can measure environmental params easily - temperature, humidity, pressure
- there are libraries for gas sensors
- there is code on the forum for PH measurements.

Furthermore assuming the bacteria are in a petri dish you can illuminate them with diferent colors (including IR and UV led) of light and measure
- reflection, absorbtion and pass through with light sensors. =>>  absorption = LIGHTIN - reflection - passthrough

- You can switch a laser "burning" the bacteria and measure new gasses.

All these measurements will change over time (or not) which indicates growthrate or productivity or ...

Of course you need to build up calibration and reference tables to interpret the data you get

(no microbiologist so all disclaimers apply :)

If the bacteria are in liquid culture, you can measure their population density as optical density. 

Mutation happens on a genetic level, so to monitor for mutation you will need a gene sequencer.  I think that is a little beyond the Arduino's capabilities.

OpenPCR is built on an Arduino. ;)

I dont have much idea about shield for arduino that could monitor bacteria but can suggest you that information related to arduino can be gathered from there site.
